Definitions

  • the invention relates to a grinding wheel with a flat, circular carrier surface on which a plurality of elongated grinding members are arranged running at least partially radially, wherein at least one discharge opening is arranged ahead of the grinding members in the circumferential rotational direction and the carrier surface has a centrally truncated conical depression extending from the grinding members.
  • the circular grinding wheel is, for example, driven by an electrical motor and removes particles, in particular dust particles, from its surface by means of grinding members arranged on a carrier surface.
  • the grinding members are formed of diamond particles, for example, so that adequate hardness is provided for working a concrete surface.
  • the carrier surface has at least discharge opening arranged ahead of the grinding members in the rotational direction. The discharge openings serve in discharging the particles, for example, by means of a low-pressure source connected to the discharge openings by a conduit.
  • the carrier surface has a centrally basically truncated conical depression facing away from the grinding member, in order to fasten the grinding wheel to, for example, a motor driven drive spindle.
  • U.S. Pat. No. 6,299,522 B1 discloses a grinding wheel comprising a flat, circular carrier surface on which a plurality of elongated grinding tips are arranged and run at least partially substantially radially.
  • a discharge opening is disposed ahead of the grinding tips in the circumferential direction and the carrier surface has a central circumferential truncated conical depression that faces away from the grinding tips.
  • the grinding tips run essentially in the circumferential direction, whereby the discharge openings are disposed in a radial zone adjacent to the grinding tips.
  • the object of the present invention is to provide a grinding wheel with grinding members that assures sufficient suction performance.
  • the object is essentially achieved according to the invention in that the discharge openings abut the grinding members in the direction of rotation and approximately over the entire length of the grinding members.
  • a discharge opening can, for example, be configured in a plurality of parts in order to assure a higher degree of stability in the grinding wheel.
  • the discharge openings extend over 75% to 100% of the length of the adjacent grinding members.
  • the discharge openings advantageously have a first width running in the circumferential direction and the grinding members have a second width running in the circumferential direction, whereby with corresponding grinding members and discharge openings the first width corresponds essentially with the second width.
  • the grinding members are preferably arranged in combination substantially in an L-shape with a longitudinal extension in the circumferential direction essentially abutting on the radial longitudinal extension in order to avoid escape of the removed particles radially outwards over the external circumference of the grinding wheel.
  • the discharge openings are formed substantially in the shape of an L.
  • the discharge openings each have a section that runs in the circumferential direction in order to assure in this fashion, especially radially outwards, sufficient suction performance.
  • FIG. 1 is a bottom view of a grinding wheel according to the invention.
  • FIG. 2 is a cross-section along the line II—II of the grinding wheel shown in FIG. 1 .
  • FIGS. 1 and 2 represent a grinding wheel according to the invention having a planar or flat, circular carrier surface 1 on which a plurality of elongated grinding members 2 are arranged running at least partially substantially radially.
  • the grinding wheel has a central axis with the carrier surface spaced radially outward from the axis.
  • a discharge opening 3 is disposed ahead of each of the combination of grinding members 2 in the circumferential direction U.
  • the carrier surface 1 has a centrally arranged substantially truncated conical depression 4 facing away from the grinding members 2 , as can be seen particularly in FIG. 2 .
  • the discharge openings 3 abut in the direction of rotation D on the combination or pair of L-shaped grinding members 2 and extend approximately over the entire length L of the grinding members 2 . Furthermore, the discharge openings 3 have a first width b 1 running in the peripheral direction U and the grinding members 2 have a second width b 2 running in the circumferential direction U, whereby in the case of corresponding grinding members 2 and discharge openings 3 , the first width b 1 corresponds basically with the second width b 2 .
  • the grinding members 2 have a longitudinal extension L 2 extending essentially in the circumferential direction U abutting the radial extending longitudinal extension L 1 .
  • the overall length L of the grinding members 2 corresponds in this arrangement to L 1 +L 2 .
  • the discharge openings 3 are basically, as in the case of the grinding members 2 , formed L-shaped and each exhibit a section 5 that runs in the circumferential direction U.
  • the depression 4 has a plurality of through holes running radially relative to the carrier surface 1 . Furthermore, the depression 4 has a receiving hole 7 running transversely to the carrier surface 1 and centrally relative to the axis of the depression 4 for fastening the grinding wheel to a motor driven drive spindle (not shown).
  • the grinding members 2 are arranged in two parts from diamonds and arranged in pairs. Of course, other hard materials are also appropriate for manufacturing the grinding wheel, including hard metal, PCD or the like. In a further embodiment (not shown) the grinding members 2 are formed in one piece.
  • the grinding members 2 comprise a substantially rectangular cross-section.
  • the inner or radially extending grinding members 2 are inclined approximately at a 45° angle relative to the diameter.
  • the portion of the grinding members 2 disposed in the circumferential direction U is disposed at the circumferentially extending radially outside edge 8 of the carrier surface 1 .
